Question

Quizplus · Accepted Answer

Individuals with HIV may contract a type of pneumonia called Pneumocystis pneumonia (PCP) which is rare in the general population. This is because HIV attacks and destroys helper T cells, which play a crucial role in the immune system's ability to fight off infections, including PCP. Without functioning helper T cells, individuals with HIV are at higher risk for developing PCP.
